INSTALLATION INSTRUCTIONS
SAFETY
For CSS-O,C ensure that all power sources
are disconnected and locked out before
installation as severe injury or death may
result from electrical shock due to contact
with high voltage wires.
This product is not intended to be used for life
or safety applications.
This product is not intended for use in any
hazardous or classified locations.
INSTALLATION
Make sure that all installations are in compliance with all
national and local electrical codes. Only qualified
individuals that are familiar with codes, standards and
proper safety procedures for high voltage installations
should attempt installation. The current switches will not
require external power, since the power for the current
switch is induced from the conductor being monitored.
The current switch may be mounted in any position using
the (2) #8 x 3/4 in. (19 mm) Tek screws and the mounting
holes in the base or snapped directly on to the 1-3/8 in.
(35 mm) DIN rail (See Figures 1 and 2). Leave a
minimum distance of 1 in. (25 mm) between the current
switch and any other magnetic devices, such as
contactors and transformers.
For applications in which the normal operating current is
below the 0.8/2.0 Amps trip point (See Fig. 3), the
conductor being monitored may be looped through the
sensor 6/12 times giving you a total operating current of
6/12 times the original current.
Example:
A small fan operating at 0.2 Amps can be wrapped
through the sensor 6 times to give you a total
operating current of 1.2 Amps flowing through the
CSS-O-A300-001. Another option is to use CSS-OA200-001.
A small fan operating at 0.2 Amps can be wrapped
through the sensor 16 times to give you a total
operating current of 3.2 Amps flowing through the
CSP-O-A300-001. Another option is to use the
CSP-O-A200-001.
3X
Never rely on the LEDs to determine whether
power is present at the current switch. The
red LED will indicate whether the current is
above the adjustable trip point. The green
LED will indicate whether the current is below
the adjustable trip point.
IMPORTANT
The current switch should be used on insulated
conductors only!

greater than 250 Amps or for conductor diameters larger
that 3/4 in. (19 mm) in diameter, and external 5 Amps

Latch Operation
Pressing down on the two (2) side tabs and swinging the
cover open opens the split core current switch as shown
in Fig. 5. Lifting up the latch with a flat-tip screwdriver as
shown in Fig. 6 can also open the unit. Press down firmly
on the cover to close the current switch. An audible “click”
will be heard as the tab slides over the tongue on the
base.
Mating surfaces of the magnetic core are
exposed when the sensor is open. Silicone
grease, present on the cores to prevent rust,
can capture grit and dirt if care is not
exercised. Operation can be impaired if
anything prevents good contact between pole
pieces. Visually check the mating parts of the
core before closing the current sensor.
